392 LIST OF MEDICINES. 



of fresh tobacco leaves cut fine, in a pound of lard over a 

 gentle fire until it becomes friable, would be an admirable 

 application on irritable ulcers of the foot or other parts. 



TURPENTINE (Spirits of) Has about the same internal 

 and external effect with tar ; but it lacks the creosote, which 

 may render it a little less effective on old ulcers. (See Tar.) 



VERDIGRIS (Acetate of Copper) Often used in hoof- rot 

 in combination with blue vitriol. Its medicinal properties are 

 very similar, and I doubt whether it forms any useful addition 

 to the former in such cases. 



ZINC (Carbonate of) Mixed with lard, constitutes a 

 valuable emollient and healing ointment. It is mixed in the 

 proportion of one part of the carbonate, by weight, to eight 

 of lead.
